Many specimens reared from a range of galls of Andricus, Aphelonyx and Cynips (Cynipidae) in the provinces of West-Azarbaijan, Lorestan, Kordestan and Kermanshah (Table 1). Exceptionally, Askew et al. (2006) mention an association of this species with the cynipid wasp Diplolepis rosae (L.) on Rosa .

Ormyrus nitidulus is widely distributed in the West Palaearctic region (Noyes 2011) although it has not been mentioned for Middle East countries (Narendran et al. 2007). It is possible that the morphospecies O. nitidulus is a complex of cryptic species, as has been reported for other parasitoids of the oak gallwasp community (Nicholls et al. 2010). It displays a moderate amount of variation and molecular analysis reveals a number of clades, but we have not been able to completely match the molecular clades to morphological forms.
